and sending, by the terminal device, Non-Acknowledge (NACK) corresponding to the downlink channel in a first slot; wherein a second slot is indicated to transmit feedback information corresponding to the downlink channel, and the second slot is different from the first slot. ## Claims ### Claim 1 A wireless communication method, comprising: receiving, by a terminal device, downlink channel transmitted in time slots; receiving, by the terminal device, an indication used for indicating the terminal device to transmit, in a second slot, feedback information corresponding to the downlink channel; determining, by the terminal device according to a result of the downlink channel, the feedback information corresponding to the downlink channel is Acknowledge (ACK); sending, in the second slot, by the terminal device, the feedback information corresponding to the downlink channel; and sending, in a first slot, by the terminal device, Non-Acknowledge (NACK) corresponding to the downlink channel; wherein the second slot is different from the first slot. ### Claim 2 (depends on 1) The method according to claim 1, wherein an ACK/NACK bit corresponding to the downlink channel is included in a HARQ-ACK codebook transmitted in the first slot. ### Claim 3 (depends on 1) The method according to claim 1, further comprising: receiving, by the terminal device, indication information used for determining an ACK/NACK bit corresponding to the downlink channel included in a Hybrid Automatic Repeat reQuest (HARQ)-ACK codebook transmitted in the first slot. ### Claim 4 An apparatus in a terminal device, comprising: a transceiver, a processor and a memory storing program instructions, wherein when the program instructions are executed by the processor, the apparatus is configured to: receive, through the transceiver, downlink channel transmitted in time slots; receive, through the transceiver, an indication used for indicating the terminal device to transmit, in a second slot, feedback information corresponding to the downlink channel; determine, according to a result of the downlink channel, the feedback information corresponding to the downlink channel is Acknowledge (ACK); send, in the second slot, through the transceiver, the feedback information corresponding to the downlink channel; and send, in a first slot, through the transceiver, Non-Acknowledge (NACK) corresponding to the downlink channel; wherein the second slot is different from the first slot. ### Claim 5 (depends on 4) The apparatus according to claim 4, wherein an ACK/NACK bit corresponding to the downlink channel is included in a HARQ-ACK codebook transmitted in the first slot. ### Claim 6 (depends on 4) The apparatus according to claim 4, the apparatus is further configured to: receive, through the transceiver, indication information used for determining an ACK/NACK bit corresponding to the downlink channel included in a Hybrid Automatic Repeat reQuest (HARQ)-ACK codebook transmitted in the first slot. ### Claim 7 A non-transitory computer-readable medium, configured to store a computer program, wherein the computer program comprises instructions for causing a terminal device to perform a wireless communication method comprising: receiving downlink channel transmitted in time slots; receiving an indication used for indicating the terminal device to transmit, in a second slot, feedback information corresponding to the downlink channel; determining, by the terminal device according to a result of the downlink channel, the feedback information corresponding to the downlink channel is Acknowledge (ACK); sending, in the second slot, by the terminal device, the feedback information corresponding to the downlink channel; and sending, in a first slot, Non-Acknowledge (NACK) corresponding to the downlink channel; wherein the second slot is different from the first slot. ### Claim 8 (depends on 7) The medium according to claim 7, wherein an ACK/NACK bit corresponding to the downlink channel is included in a HARQ-ACK codebook transmitted in the first slot. ### Claim 9 (depends on 7) The medium according to claim 7, wherein the method further comprises: receiving indication information used for determining an ACK/NACK bit corresponding to the downlink channel included in a Hybrid Automatic Repeat reQuest (HARQ)-ACK codebook transmitted in the first slot.
